Application filed January, 1909. Serial No. 474,343. I a

To all'whom it may concern citizen of the United States, residing at- Yorktown, in the county of Lincoln and State of Kansas, have invented certain new and useful Improvements in Chain-Manipuspecification.

This invention relates to lating tools. 7 I

In the use of thresher and similar machines, the chains thereof frequently become broken incident to the links becoming sepachain manipumend or con lo the links of the chain together, resulting in the threshing operation being stopped for such a period as' to cause considerable loss to the thresher by virtue of the fact that his employees are thrown out of work and also'because during the time larly adapted for use in mending. or coupling chains under the above conditions, and also especially designed for the urpose of tightening or loosening chains 0? threshers or other machines or devices.

With theabovefand other objects in view,

nation and arran ement of parts hereinafter more fully described, illustrated in the accompanying drawings and particularly pointed out in the appendedclaims, it being understood that. changes may be, made in without departing from-the spirit or"sacri 1fsicing any of the advantages of the invenion.

The character 6 indicates a jaw havin an opening 7 formed therethrough for a mement witlithe opening" 3 in the jaw 2, and these openings 3 and 7 are designed to receive the heads8 and 9, respectively, of a link 10 designed to couple the jaws together. The heads 8 and 9 of the link 10 are perfo- 'rated for the passage therethrough ofthe pins 11, whereby the jaws may have pivotal connection with said links.

At oneend the jaw 6 is bifurcated, as indi- Patented Nov. 9, 1909. I

cated at 12, to embrace the cam '13 at the inner end of the handle 14, and the jaw 6 is pivotally connected to the cam 13 eccentrically of the latter by means of a pivot pin' -15, there being perforations '16 in the cam13 whereby the jaw 6 may be adjustably connected to the cam according to the size of the chains to be jo erated upon or for other reasons. It will e observed that 1 the cam 13 bears u on the jaw 2 approximately at the base 0 the handle 1, as early shown in Figs. 1 and 3.

In order to force the jaws normally a art,

I provide a spring 16 having one en secured' to the jaw 2 by means of a suitable fastening' -17 with its opposite end slidably bearing'against the inner face of the jaw 6 slightly in the rear of the transverse grooves 18. and19 formed in'the latter jaw for cooperation with the aforesaid transverse grooves 4-. and 5 to receive the transverse part orp n of the ordinary chain.- The, s ring 16 is provided with a slot 20 adapte to embrace the link 10 in such a way as to hold the aw 6 and the handle 14 in alinenient-with the jaw '2 and the handle 1, respectively, and also for the purpose. of maintaining the cam 13 in true posit on upon the'jaw 2. a

.In the asset thejtool, when two links a [andflb of a chainhavebecome separated, the

tool is engaged over the tongue 0 of link a to clampthe-tongueover the bightdof link I). so thatlthe two links cannot be separate manner 'descri ed.

What is claimed is i 1. A tool of the character described comprising a handle provided at one end d 'under a pullin action. The tongues of the upon the f' ios easy tightenin together of the lin s in the with a jaw, a second aw, a link ivotally I connected to'the jaws, a second han le member provided at its inner end with a cam for engagement with the first mentioned jaw and plvotally connected to the second jaw whereby the outer ends of the jaws {may be forced toward and away from each other, each jaw having a transversegroove in its inner face, and a spring secured to one of the jaws and bearing against the other jaw and provided with a slot intermediate its ends to embrace said link.

2. A device of the character describedcomprising a handle provided at one'end with a jaw having an opening therein, .a second jaw having an opening therein, a link having its ends fitted in the openings of the jaws and pivoted therein, a second
